That's what COBOL 75, IIRC, was supposed to eliminate--no "extensions"
unless specifically enabled. The Navy audit tests of that time checked
for "extended" behavior and would fail you if something sneaked through.
I mean, in the world of standard COBOL, what the hell is a COMP-5?
FORTRAN at about the same time was suffering similar "vendor enhancement
creep". CDC FORTRAN certainly had its share, including one of two
"enhancements" that could lead to ambiguous statements. Univac had
FORTRAN V. (Internally, IBM initially called PL/O "FORTRAN VI"). It
was getting pretty bad.
Later FORTRAN/Fortran standards mandated that any standard FORTRAN had
to have the capability of compiling and running the standard and
flagging anything not conforming to the standard.
Which was pretty useless.the original author of a program set out from
the beginning to write a portable program. Otherwise, the typical
programmer is going to enable all the bells and whistles and leave it to
some poor sod in the future to handle cross-platform issues.
BASIC is perhaps the worst. How many widely-used BASICs conform to
X3.113-1987? Visual BASIC? Ha!
